Cov Kav Dej Calcium Silicate, Npaj Txhij Rau Kev Xa Khoom ~

Kev Taw Qhia
Cov yeeb nkab calcium silicate yog ib hom khoom siv rwb thaiv tsev tshiab ua los ntawm silicon oxide (quartz xuab zeb, hmoov, silicon, algae, thiab lwm yam), calcium oxide (tseem muaj txiaj ntsig lime, calcium carbide slag, thiab lwm yam) thiab cov fiber txhawb zog (xws li cov mineral wool, iav fiber, thiab lwm yam) ua cov khoom siv tseem ceeb, los ntawm kev sib tov, cua sov, gelling, molding, autoclaving hardening, ziab thiab lwm yam txheej txheem. Nws cov khoom siv tseem ceeb yog cov av diatomaceous thiab lime uas ua haujlwm heev. Hauv qab qhov kub thiab txias thiab siab, hydrothermal reaction tshwm sim los ua kom cov khoom npau, thiab cov mineral wool lossis lwm cov fibers raug ntxiv ua cov neeg sawv cev txhawb zog, thiab cov ntaub ntawv coagulant raug ntxiv los tsim ib hom khoom siv rwb thaiv tsev tshiab.

Cov ntawv thov
Cov yeeb nkab calcium silicate yog ib hom tshiab ntawm cov khoom siv rwb thaiv tsev dawb tawv. Nws muaj cov yam ntxwv ntawm lub zog sib dua, lub zog siab, kev ua kom sov tsawg, tiv taus kub siab, tiv taus corrosion, txiav thiab sawing. Nws yog dav siv rau hauv kev rwb thaiv tsev thermal thiab hluav taws kub rwb thaiv tsev ntawm cov khoom siv kav dej, phab ntsa thiab ru tsev hauv fais fab, metallurgy, petrochemical, cement manufacturing, kev tsim kho, kev tsim nkoj thiab lwm yam lag luam.

Cov qauv khoom
Cov yeeb nkab calcium silicate yog cov khoom siv rwb thaiv tsev thermal uas ua los ntawm cov thermoplastic reaction ntawm calcium silicate hmoov thiab sib tov nrog cov inorganic fibers. Nws yog cov khoom siv rwb thaiv tsev ua haujlwm siab uas tsis muaj asbestos, uas tuaj yeem muab kev tiv thaiv rwb thaiv tsev zoo rau cov kav dej kub siv hauv cov chaw tsim hluav taws xob, cov nroj tsuag petrochemical, cov chaw ua roj, cov tshuab faib cua sov thiab cov nroj tsuag ua tiav.

Cov yam ntxwv ntawm cov khoom
Qhov kub siv tau zoo yog txog li 650 ℃, uas yog 300 ℃ siab dua li cov khoom siv iav zoo heev thiab 150 ℃ siab dua li cov khoom perlite nthuav dav; qhov kev ua kom sov yog qis (γ≤ 0.56w / mk), uas qis dua li lwm cov ntaub ntawv rwb thaiv tsev nyuaj thiab cov ntaub ntawv rwb thaiv tsev sib xyaw ua ke; qhov ceev ntawm cov khoom me me, qhov hnyav yog qhov qis tshaj plaws ntawm cov ntaub ntawv rwb thaiv tsev nyuaj, cov txheej rwb thaiv tsev tuaj yeem nyias dua, thiab lub bracket nruj tuaj yeem txo qis thaum lub sijhawm tsim kho, thiab kev siv zog ntawm kev teeb tsa yog qis; cov khoom rwb thaiv tsev tsis muaj tshuaj lom, tsis muaj ntxhiab, tsis kub hnyiab, thiab muaj lub zog kho tshuab siab; cov khoom tuaj yeem siv ntau zaus rau lub sijhawm ntev, thiab lub neej kev pabcuam tuaj yeem ntev li ntau xyoo yam tsis txo cov cim qhia kev siv tshuab; kev tsim kho muaj kev nyab xeeb thiab yooj yim; qhov tsos yog dawb, zoo nkauj thiab du, nrog kev khoov zoo thiab lub zog compressive, thiab poob me me thaum thauj mus los thiab siv.
